Problems solved by technology

[0005] The invention provides an intelligent automatic fume hood for laboratories, which aims to solve the problem that the current fume hood generally uses the power of the air pump to collect the gas that is harmful to the human body through the suction hood according to the characteristics of the gas floating upwards. The gas hood is generally set at the top, and there is still some distance from the experimental reactants. In this way, because the gas floats upward, there will be more or less leakage during the gas collection process, which will cause adverse effects on the operator. problem of influence

Abstract

The invention is suitable for the technical field of laboratory related facilities, and provides an intelligent automatic ventilation cabinet for a laboratory, the intelligent automatic ventilation cabinet comprises a main cabinet body, a placing main board for placing laboratory supplies is fixedly connected in the main cabinet body, and a gas collecting assembly is also arranged in the main cabinet body. When the experiment articles placed on the placing main plate react, the air collecting pump is started, external air is collected into the collecting box through the first funnel, the first collecting pipe and the second funnel under the suction effect of the air collecting pump, and air pressure difference is generated above the first funnel due to air flow; harmful gas generated during reaction of experiment articles placed on the placing main plate is collected into the collecting box through the first through hole, the first funnel, the first collecting pipe and the second funnel under the action of gas pressure, so that the harmful gas is effectively prevented from floating upwards, the harmful gas is directly collected, the structure is simple, the operation is simple, and the practicability is high. And the practicability is very high.

Description

technical field [0001] The invention belongs to the technical field of laboratory-related facilities, and in particular relates to an intelligent automatic fume hood for a laboratory. Background technique [0002] Laboratory ventilation is an indispensable part of laboratory design. In order to prevent laboratory workers from inhaling some toxic or unknown toxic substances and organisms, the laboratory should have good ventilation. The fume hood is the most important part of the laboratory. There are many types of local exhaust equipment commonly used. Because of their different structures and different conditions of use, their exhaust effects are also different. [0003] Existing fume hoods are generally of a fixed structure. After being assembled, they are placed in one place. When it is necessary to perform experimental operations, the relevant reaction materials can be placed on it for reaction. However, the current fume hoods are generally based on The characteristics ...
